ROY C. BIBLE ZQMW ATTORNEY United States Patent 1 2,734,296 ADJUSTABLE CHART OR MAP HOLDER Roy C. Bible, Cheyenne, Wyo. Application July 30, 1952, Serial No. 301,774 1 Claim. (Cl. 40-86) This invention relates to a holder for charts and maps, and especially to a holder that is adjustable by oscillation to two or more positions for normal and convenient view- More particularly, the present invention is concerned with a holder designed to receive material in strip form, portions of the strip possibly being at right angles to others and even in an upside down relationship.

It is my primary object to devise an apparatus for positioning maps, charts and the like for correct viewing of the pictorial representations or the data thereon. Especially, it is an object to handle a roll of interconnected maps and/ or charts that are unlike in the sense that some of them may be tilted or reversed relative to the others.

Another object of the invention is to provide a map box that can be mounted for oscillation to a plurality of fixed positions, and in this connection to incorporate means for detachably mounting the box on a support.

These and further objects will be understood from a study of the following description and the accompanying drawing, wherein:

Figure l is a face view of a preferred embodiment;

Figure 2 represents a cross section taken on the plane of line 2-2 of Figure 1;

Figure 3 is a fragmentary view in rear elevation of the box of Figures 1 and 2, removed from its support;

Figure 4 is a section taken on line 4-4 of Figure 3, the support being incorporated;

Figure 5 is a front view of the support;

Figure 6 is a top plan view of the support; and

Figure 7 shows the apparatus, in front elevation, after the box has been shifted 90 degrees on its supporting axis.

With continued reference to the drawing, there is shown a pair of standards 8 attached to and supporting a rectangular plate 9. These standards may be modified or omitted altogether. Some other means may take the place of the plate, whose only purpose is to provide a fixed support for a cylindrical cup 10. This cup is secured in any suitable manner, as by screws 12, to the board 9.

The rim of the cup has at least two notches 13 formed therein perpendicular to the base (four being illustrated), 90 degrees apart for a purpose presently seen. A spindle 14, coaxial with the rim and welded or otherwise secured to the cup base, extends forwardly to provide a pivotal support for a map box. Its free end is annularly channeled at 15 and telescopic with a sleeve 16.

This sleeve therefore is rotatably supported by the spindle. It in turn supports, through a plate 17 and screws 18, the chart-backing board 19 of a map box that further comprises parallel elements 20 secured to the board and a rectangular frame 22 mounted by and surrounding said elements in such manner as to provide a pair of parallel transverse receptacles 23 for a pair of the usual map rollers 24. At the front of the box these receptacles may be closed by strips 25 which may be considered as representing the bottom of the box, leaving an opening 26 through which portions of a wound strip 27 may be viewed. In conventional manner the rollers have cranks 28, and frictional springs 29.

The strip 27 may comprise numerous interconnected sections of maps, photographs, charts etc. Figure 1 shows two such elements, A and B, preferably connected together by a special contiivance 30, as fully disclosed in my copending application Serial No. 294,411, filed June 18, 1952, now abandoned. Section A can be read 2,734,296 Patented Feb. 14, 1956 normally, but the top and bottom of section B stand vertically and hence it cannot be viewed quickly or easily. Therefore when E follows A into position behind the opening 26, the box is manually turned degrees clockwise to the position seen in Figure 7. If picture B had been in reverse, right to left, then the box would have been oscillated 90 degrees in the opposite direction. Had the picture been upside down, a shift of degrees would have been necessary, and this is why four notches 13 are shown in Figure 5. 9

These notches or holes 13 cooperate with the finger 32 of a bell crank 33 pivoted on a bracket 34 and having an externally manipulating knob 35. Normally the finger is in any one of the holes and is held there by a tension spring 36 so that the box is latched in a selected position. By pulling the knob outward the box may be oscillated to any other of the three remaining positions.

It is preferable to lock the box axially onto the spindle mount, but to do so in such manner that it can be readily removed. To this end, the tip of an axially slidable rod 37 cooperates with the channel 15 of the spindle 14, gaining access to the latter through a hole 38 in the sleeve 16. The rod extends through a bracket 39 and outwardly through the box to a pull knob 40. A compression spring 42 has one end reacting against this bracket and its other end piercing the rod, thus biasing the rod tip into the groove 15. Obviously by pulling on the rod the box can be removed or replaced.

As is customary, I wish to be limited only by a reasonably liberal interpretation of the appended claim.

What is claimed as new is:

A device for supporting and shifting a strip chart or the like, and for permitting the chart to be turned about an axis perpendicular to its plane and for latching it in any desired rotary position, comprising in combination a chart box having two sides and two ends assembled to form an elongated rectangle, a bottom member attached to the edges of the sides and ends on one side, and provided with a central opening, a chart backing board of a size substantially equal to the opening in the bottom, having two edges attached to the sides of the box and so positioned relative to the bottom member that its outer surface is substantially coplanar with the inner surface of the bottom, and of an area substantially equal to the opening in the bottom, the length of the opening being less than the length of the box leaving a space at each end for a chart roller, a roller positioned in each of said spaces and journaled for rotation in the sides, a strip type chart having its ends attached to said rollers, means comprising a crank operatively attached to each roller for turning it to shift the chart, a spring pressed friction device operatively associated with each roller resisting rotation thereof, means supporting said box for rotation in its plane, comprising, a pivot attached to the rear surface of the chart backing board, and an elongated bearing attached to a stationary support, and means for latching the box in any of several rotary positions.
